A. Calculate the force on an alpha particle in an electric field E=Exm where E=3.6E4 N/C and x is a unit vector in the x direction. What is the direction of the force?
B. Calculate the acceleration of the alpha particle in this electric field. What is the direction of the acceleration?

For part A what I did was:
F=qE=2(1.60E-19 C)(3.6E5N/C)=1.152E-13 to the positive x direction
